Question 73888
Using the index of a sequence as the domain and the value of the sequence as the range, is a sequence a function? 
Yes
------------------
Include the following in your answer: 
Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic sequence? 
arithmetic is linear because a(n)=d(n-1)+a(1). d is the slope and a(1) is the
y-intercept.
----------------
Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric sequence?
geometric is exponential because a(n)=(a(1))r^(n-1)
---------------

Give at least two real-life examples of a sequences or series. 
One example should be arithmetic:
You deposit $100 in a piggy bank and add $10 dollars each week.
Your savings is an arithmetic sequence where a(1)=100 and d=10.
-----------
the second should be geometric:
You deposit $100 in a bank and receive the money compounded at
8% annual interest applied yearly.
The value of your savings is a geometric sequence where a(1)=$100
and r=1.08
